ABSTRACT

During intensive culture of South-American catfish, Rhamdia sapo fingerlings an epizootic similar to fin rot was developed. Aeromonas hydrophila and Pseudomonas aeruginosa were isolated and they were treated and controlled with daily short dip, 1 ppm Furanace. The disease was experimentally reproduced and we concluded that it is result of interaction of unfavorable environment conditions such as low dissolved oxygen, increase of solids in suspension; host condition and the presence of Aeromonas hydrophila and Pseudomonas aeruginosa.
